It delivers single-qubit gate fidelity of 99.9975 percent and two-qubit gate fidelity of 99.921 percent, the highest figures reported in any commercial system so far.<\/p>\n<p>Lead architect Dr. Anthony Ransford said, \u201cYou would need to harvest every star in the universe to power a classical machine that could do the same calculations.\u201d<\/p>\n<p>In benchmark tests using Random Circuit Sampling (RCS), the same method used by Google to demonstrate quantum supremacy, Helios achieved results that would be practically impossible for any classical supercomputer.<\/p>\n<p>Quantinuum reported that matching its performance would require more power than the Sun produces, while Helios completed the task using roughly the energy of a single data center rack.<\/p>\n<p>Scalable architecture and new ion design<\/p>\n<p>Helios introduces a new ion-trap architecture that switches from ytterbium to barium qubits. The use of visible-light lasers instead of ultraviolet reduces costs and improves reliability. <\/p>\n<p>Barium also enables the system to detect and remove certain types of atomic-level errors, improving computation quality.<\/p>\n<p>The system\u2019s ion trap features a junction-based Quantum Charged Coupled Device (QCCD) layout that routes qubits efficiently. This allows cooling, sorting, and computation to occur in parallel, improving both speed and accuracy. <\/p>\n<p>Chief Scientist Dr. John Gaebler said the design, first drawn as a napkin sketch, was \u201cincredible to see realized after all the team\u2019s work.\u201d<\/p>\n<p>Real-time programming and fault tolerance<\/p>\n<p>Helios introduces a real-time control engine that allows programs to adapt as they run. <\/p>\n<p>It can interleave GPU-accelerated classical and <a href=\"https:\/\/interestingengineering.com\/science\/tokyo-researchers-quantum-squeezing-nanoscale\" target=\"_blank\" rel=\"dofollow noopener\">quantum<\/a> computations within a single program, enabling faster problem-solving and more flexible algorithms.<\/p>\n<p>The system converts 94 of its 98 physical qubits into logical ones, fully entangled in one of the largest GHZ states ever recorded. <\/p>\n<p>These logical qubits, built on Quantinuum\u2019s Iceberg code, achieve near break-even fidelity, meaning they outperform unencoded physical qubits.<\/p>\n<p>Helios also achieved 48 fully error-corrected logical qubits at a 2:1 encoding rate, a result once thought impossible.<\/p>\n<p>Competing systems would require thousands of qubits to reach the same level of fault tolerance.<\/p>\n<p>With Helios, Quantinuum has positioned itself at the forefront of practical quantum <a href=\"https:\/\/interestingengineering.com\/science\/unique-method-simulates-error-corrected-quantum-computations\" target=\"_blank\" rel=\"dofollow noopener\">computing<\/a>, combining scientific breakthroughs with a design ready for real-world deployment.<\/p>\n","protected":false},"excerpt":{"rendered":"Quantinuum has introduced Helios, its most advanced quantum computer yet, setting new records in performance, fidelity, and scalability.&hellip;\n","protected":false},"author":2,"featured_media":123270,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[24],"tags":[86220,86221,41089,86222,111,139,69,393,11009,375,86223,147],"class_list":{"0":"post-123269","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-physics","8":"tag-barium-qubits","9":"tag-fault-tolerant-quantum-computer","10":"tag-helios","11":"tag-ion-trap","12":"tag-new-zealand","13":"tag-newzealand","14":"tag-nz","15":"tag-physics","16":"tag-quantinuum","17":"tag-quantum-computing","18":"tag-quantum-fidelity","19":"tag-science"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/123269","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=123269"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/123269\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/123270"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=123269"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=123269"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=123269"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
